Any scouting reports on bathrooms at the bottom of GMR in the Glendora area? Staged at the Goddard Middle School (less than a mile from where GMR starts), but it didn't seem to have open bathrooms (despite the fact that there were youth soccer games going on...). Yeah, I can pee in the bushes, but some of the ladies I ride with want other options.

Pioneer Park is on Sierra Madre just east of hwy 39, (Azusa Canyon), and has nice bathrooms. It's about 3 miles west of GMR, but the construction forces you to go around, for now.

I practically always make a stop there since I prefer to climb 39 and East Fork rather than GMR. Last year on a rainy weekday when I was using the urinal, I was followed into the bathroom and propositioned by a rather desperate, seemingly homeless drug addict/prostitute, while her old man pimp/father? stood guard at the door. I still stop there and the bathrooms are usually clean, just keep your eyes open. If you're driving Encanto is also a good option, you will just add a couple of miles to your ride which shouldn't hurt.
